- Scan file and output strings to `messages.po`:

`xgettext {{path/to/input_file}}`

- Use a different output filename:

`xgettext --output {{path/to/output_file}} {{path/to/input_file}}`

- Append new strings to an existing file:

`xgettext --join-existing --output {{path/to/output_file}} {{path/to/input_file}}`

- Don't add a header containing metadata to the output file:

`xgettext --omit-header {{path/to/input_file}}`
